This is called ICC (Inter-Client Communication) in X parlor, the
respective manual (ICCCM) is often called the most important, least
read and least understood of all X protocol specifications.

Just ssh somewhere, with X forwarding, and call xlsclients. It will
list all running applications that have a window open on your X
server. And every connected application will see every other
application that's also connected to that X server and be able to
communicate with it.

That does not mean that other users on that remote system will see
your applications. The applications that *you* call while *you*
have a connection to that X server active sees them. (Though the
realization is not terribly secure -- root on the remote system can
connect, too.)

That's how network-transparent copy&paste is implemented, for
example. (For proper C&P, apps must be able to communicate to
bargain over supported and needed representions and encodings.)
